Make a script/web extension that allows for simple mod.io url integration

[AichiChikuwa]

possible implementation:

• the script/extension adds a button to the mod.io mod page.
• when the script/extension's button is clicked, the url with a special identification string (may be something like "extension_url_link: ...") is copied to the clipboard.
• the app tracks the clipboard, and when it finds out that the clipboard contains that identification string, it gets the url and do the add mod thingy.
• *since the solution utilizes user's clipboard, the script/extension would probably need a one-time warning to let the user know that their clipboard is being tracked and will replace its content when the button is clicked.
